Vapur believes that clean tap water is the best drinking water for you, your community and the planet. So we set out to design the most portable reusable water bottle on the planet. By making tap water more portable, we hope to make bottled water obsolete. Unlike rigid water bottles, Vapur is completely collapsible. This means it goes more places and fits in tighter spaces than any other bottle. Whether you are hiking the trails, passing though airport security or visiting the museum with your family, Vapur makes water infinitely portable.
